Jtag, Am I Screwed?
« on: July 05, 2010, 03:36:00 AM »
Im new to jtagging and had a 360 that had red rings on it with kernel 6xxx. I fixed rrod, soldered a nand-x in place got about 5 copies of my nand (no issues, all the same) and then ran xell. I got the e79 error, did some research and found that you need 7371 to jtag. So I removed xell, updated to 7371 and then like a complete muppet I wrote xell without taking a new read of my nand!

Now i'm getting rrod again and nothing on the screen. Is there anything I can do to fix this or is it bricked?

Thanks for any info.

You don't need 7371 to jtag, you need 7371 or below. You should still be able to read/write the nand

If you read the NAND four times, then simply rewrite that original NAND back on there and start the process all over again.

Also I'm not sure why you updated to 7371?  (IMG:style_emoticons/default/uhh.gif) You should be able to read the NAND, put Xell on and get your keys, and then flash with freeboot.

I thought I read in someone else's post (very similar issue) and they were told to update the kernel. Oh well. Sorry for another noob question but Im using Jtag Tool by coolshrimp, how would one go about writing their original image back on to the nand?

Just click "Remove XELL" then select your NAND Dump.

Thanks dude, i realised afterwards, damn I felt stupid! Still had issues with the e79 error. Gonna try it with xbreboot, but I'm not getting my hopes up.

That's weird. With original unmodded dump right? You obviously dont need jtag wires on original nand so I'm thinkin X-Clamp fix or something similar may help. Like Xecuter's fix or something. I'm no expert but I do think that's what can fix it.

Not E79.

Which nand is on there now?
